example with 1024 drives - 4, 8, 16 are GCD factors. With 16 drives we get a total of 64 possible sets, with 8 drives we get a total of 128 possible sets, with 4 drives we get a total of 256 possible sets. So algorithm automatically chooses 64 sets, which is *16* 64 = 1024* drives in total.

- *If total number of nodes are of odd number then GCD algorithm provides affinity towards odd number erasure sets to provide for uniform distribution across nodes*. This is to ensure that same number of drives...

# Розширення OpenAPI { #extending-openapi }

У деяких випадках вам може знадобитися змінити згенеровану схему OpenAPI.

У цьому розділі ви побачите як це зробити.

## Звичайний процес { #the-normal-process }

Звичайний (типовий) процес такий.

Застосунок `FastAPI` (екземпляр) має метод `.openapi()`, який має повертати схему OpenAPI.

        LdapManager ldapManager = new LdapManager();
        ldapManager.init();

        // Edge cases
        assertEquals("", ldapManager.replaceWithUnderscores(""));
        assertEquals("normal", ldapManager.replaceWithUnderscores("normal"));
        // Input "//\\[]:;" has 8 special characters that should be replaced
        assertEquals("________", ldapManager.replaceWithUnderscores("//\\\\[]:;"));
    }

while still insisting that races are errors and that tools can diagnose and report them.

<h2 id="model">Memory Model</h2>

<p>
The following formal definition of Go's memory model closely follows
the approach presented by Hans-J. Boehm and Sarita V. Adve in
“<a href="https://dl.acm.org/doi/10.1145/1375581.1375591">Foundations of the C++ Concurrency Memory Model</a>”,

## The normal **FastAPI** app { #the-normal-fastapi-app }

Let's first see how the normal API app would look like before adding the callback.

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

This part is pretty normal, most of the code is probably already familiar to you:

## O aplicativo **FastAPI** normal { #the-normal-fastapi-app }

Vamos primeiro ver como o aplicativo da API normal se pareceria antes de adicionar o callback.

Ele terá uma *operação de rota* que receberá um corpo `Invoice`, e um parâmetro de consulta `callback_url` que conterá a URL para o callback.

Essa parte é bastante normal, a maior parte do código provavelmente já é familiar para você:

	// Retrieves information about the amount of space that is available on a disk volume,
	// which is the total amount of space, the total amount of free space, and the total
	// amount of free space available to the user that is associated with the calling thread.
	GetDiskFreeSpaceEx = kernel32.NewProc("GetDiskFreeSpaceExW")

Doğrudan çağırdığınız diğer yardımcı fonksiyonları normal `def` veya `async def` ile tanımlayabilirsiniz ve FastAPI onları çağırma biçiminizi etkilemez.
